Pci Express SSD vs. Internal SSD

[intelinarizona]

My situation in a broad aspect is as follows.

Is there a difference in *speed* between using a sata internal ssd vs a pci express slot ssd?

Would it be worth it to purchase a decent small sized pci-express ssd and swap out my small hdd with my external 1tb hd? And just use the ssd as a boot drive?

I am in Afghanistan and all I do is watch movies and tv shows on my laptop, but I am sick of having wires hanging all over the place, if I can just but the tb hdd inside my laptop and use the pci-express slot as my ssd boot drive, then in theory it make sense, and it should be alot faster than what my current hdd.

If I am wrong please let me know, as I am in the beginning stages of this, or if someone else has done this also help me out.

I heard you have to mod your bios for it to recognize the express slot as a boot device as well. Is this correct?

And is it worth it to get rid of the wires and sacrifice speed, or is there not a huge difference in speed between the internal and express cards..

Thanks for the help!

The PCIe works at a data rate of 250MB/sec (minimum) which should be enough for most SSDs. Question, however, is whether you will really get any benefits from an SSD for watching movies and TV. Typically you would use the SSD for the OS and boot times and program calls will be faster. But for movies and TV I do not see a real advantage.

I appreciate your input. The advantage would be that my 1tb internal Hdd is almost full, so I would want my OS booting off a completely separate drive, also internal. Since my laptop does not support dual Hdd then my only other option would be to boot off a Pci-express Ssd... Correct?

"Edit"

I might be talking about to different things here. Can you put a SSD into the express card slot of your laptop, and if so what is the connection speed etc. you will be attaining.
